AF diagnosis is typically based on the electrocardiogram (ECG) evaluation in hospitals or in clinical facilities. The aim of the present work is to propose a new artificial neural network for reliable AF identification in ECGs acquired through portable devices. A supervised fully connected artificial neural network (RSL_ANN), receiving 19 ECG features (11 morphological, 4 on F waves and 4 on heart-rate variability (HRV)) in input and discriminating between AF and non-AF classes in output, was created using the repeated structuring and learning (RSL) procedure. RSL_ANN was created and tested on 8028 (training: 4493; validation: 1125; testing: 2410) annotated ECGs belonging to the \u201cAF Classification from a Short Single Lead ECG Recording\u201d database and acquired with the portable KARDIA device by AliveCor. RSL_ANN performance was evaluated in terms of area under the curve (AUC) and confidence intervals (CIs) of the received operating characteristic. RSL_ANN performance was very good and very similar in training, validation and testing datasets. AUC was 91.1% (CI: 89.1\u201393.0%), 90.2% (CI: 86.2\u201394.3%) and 90.8% (CI: 88.1\u201393.5%) for the training, validation and testing datasets, respectively. Thus, RSL_ANN is a promising tool for reliable identification of AF in ECGs acquired by portable devices.<\/jats:p>","DOI":"10.3390\/s20123570","type":"journal-article","created":{"date-parts":[[2020,6,24]],"date-time":"2020-06-24T08:54:50Z","timestamp":1592988890000},"page":"3570","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":54,"title":["Artificial Neural Network for Atrial Fibrillation Identification in Portable Devices"],"prefix":"10.3390","volume":"20","author":[{"given":"Daniele","family":"Marinucci","sequence":"first","affiliation":[{"name":"Department of Information Engineering, Universit\u00e0 Politecnica delle Marche, via Brecce Bianche 12, 60131 Ancona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9152-7216","authenticated-orcid":false,"given":"Agnese","family":"Sbrollini","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, Universit\u00e0 Politecnica delle Marche, via Brecce Bianche 12, 60131 Ancona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilaria","family":"Marcantoni","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, Universit\u00e0 Politecnica delle Marche, via Brecce Bianche 12, 60131 Ancona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8327-8379","authenticated-orcid":false,"given":"Micaela","family":"Morettini","sequence":"additional","affiliation":[{"name":"Department of Information Engineering, Universit\u00e0 Politecnica delle Marche, via Brecce Bianche 12, 60131 Ancona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9801-2760","authenticated-orcid":false,"given":"Cees A.","family":"Swenne","sequence":"additional","affiliation":[{"name":"Cardiology Department, Leiden University Medical Center, P.O.
